Specification of Letters Patent.

Patented Aug. 11, 1914.

Application filed May 2, 1912. Serial No. 694,669.

To all whom it may concern:

Be it known that I, JOSEPH L. WARE, of St. Paul, Ramsey county,Minnesota, have invented certain new and useful Improvements inBinder-Heads, of which the following is a specification.

My invention relates to means for securing a cord around a bundle ofgrain, corn, hay, or other material,-and is designed as an improvementover a portion of the mechanism shown and described in my pendingapplication filed May 1, 1909, Serial No. 493,325.

My invention consists generally in various constructions andcombinations, all as here inafter described and particularly pointed outin the claims.

In the accompanying drawings forming part of this specification, Figure1 is a ver tical sectional view through'a, binder with by inventionparts in their normal position before the movement of the needle to bindthe bundle, Fig. 2 is a similar View showing the position of the partswhen the needle has carried the cord around thebundle and the parts arein position to place the clip on the crossed portions of the cord, Fig.3 is a detail sectional view, showing the operating parts of the binderhead in their normal position, Fig. 4 is an end view of the. same, Fig.5 is a view, partially in section, taken on the opposite side of thebinder head from the View shown in Fg. 3, Fig. 6 is a vertical sectionalview illustrating the mechanism for feeding the ribbon, Fig. 7 is ahorizontal sectional view showing the position assumed by the partspreparatory to the operation of folding the clip around the cord, Fig. 8is a detail view, partially in section, showing the position of theparts when the folding operation has been completed, Fig. 9 is a detailview of one of the jaws, Fig. 10 is a detail view of the cord severingknife, Fig. 11 is a similar view, showing the operation of the combinedsevering knife and cord holder, Figs. 12 and 13 illustrate the manner'ofplacing the clip on the cord.

In the drawing, 2 represents the deck of a binder, 3 the needle, 3 apacker arm, the operation of the needle and the packer. arms,

being controlled by the trip lever 4 operated through mechanism at theopposite side of applied thereto, showing the the deck in the usualwayon machines of this type.

knotter head usually employed with a binder is mounted. The frame 6 ofthe binder has a hub 7 that is adapted to slip on to the shaft 5, and onthis frame the clip forming and folding mechanism is mounted. A disk 8is secured on the shaft 5 and provided with cam surfaces which I willdesignate by reference numerals 9 and 10. A plate 11 is secured to oneside of the disk and projects radially thereon toward its periphery. Alever 12 is pivotedat 13 on the hub 7 and is provided with a projectingarm 14 having thereon and spaced apart suiiiciently to receive the edgeof the disk 8 so that in the revolution of the disk the lever 12 will beoscillated back and forth. 1

A plunger 17 is arranged to slide hori Zontally between a fixed jaw 18provided has a longitudinal a cutting edge 26 near aslot 27, throughwhich the metallic ribbon 28 is fed.

The mechanism which I prefer to employ for this feeding operationcomprises a lower 7 roll 29, an upper roll 30 having a gear connection31 with the lower roll, said lower roll being pivoted at 32 and providedwith a lever 33 and a spring 34 hearing on said lever and holding theroll 29 in contact with the roll 30 with a yielding pressure. The

roll 30 is journaled in a wall 35, while the roll 29 is free tooscillate 'on its pivotal support. These rolls are preferably arrangedwithin a chamber 36 having a door 37 leading thereto and in the upperpart of this chamber a lever 38 is mounted, having one end adapted tobear on the knife 20 and provided with a dog 39 at its other end whichanti-friction rollers 15 l and 16 mounted with a longitudinal guide-way19 and an I upstroke of the knife ing the depression s.) The '40 42 andwing movement of this knife will tilt the "lever 38,=.-revolve the rollsto feed the ribbon be tween them and on the downward move- 15' ment ofthe knife the spring 41 'will lift the dog 39 so that it will againcatch the teeth of the upper'roll to feed the'ribbon on the The plate11,' durof theknife 20, bears on one of the rollers 44 and holds theknife in 7 its depressed positionso that-it forms a portion of theguide-way for the plunger during the operation of passing the cliparound the cord.

At the forward end of the stationary jaw is a curved 7 7 also having acurved face and the face 45 the cord the operation of placing the clipthereon. The jaw 46 is mounted on' a lever I anti-friction roller .50that is'engaged'by the cam surface 10 on the disk 8 and rocked at apredetermined point in the operation of the mechanism to move the jaw 46forward to rip the crossed portions of the cord and hold'them firmlyduring the operation of.

folding the clip around the cord; 1 (See Fig. lever 48 has apart betweenthe pivot 49. and the roller 50 that is slightly flexible to compensatefor any variation in the thickness of the cord that is gripped be tweenthe movable and stationary jaws. This lever also has a spring 48 (seeFig. 3) whichnormally tendsto hold the movable jaw in its retractedposition. The'jaw 46 is preferably composed of plates spaced apart, asindicated in Fig. '9, having grooves or re- -cesses in their. edgeswhich are adapted to receive the end of the clip and guide it around thecrossed portions of thecord, and each plate has a projecting toe portionoperatingto guide the crossed portions of the cord against the'curv'edface 47 and cooperate with the fixed jaw to hold the portions of thecord securely while the clip is being clamped thereon.

At the lower end of the jaw 46 is a stud 51 which enters a slot 52 in adisk 58 pivoted at 54 on the frame of the binder head. Then this jaw 46movesforward toward the cord,

. this disk will be rotated to'swing in under the cord and lift itupso'that the lower end of the movable jaw will pass under the cord andguide it into the curved faces of'the face 45 and opposite this aw is "amovable jaw 46, i 47, between which is gripped during 48 pivotedat 49and having an:

jaws. Backward movement ofthe disk 53 is limited by a stop 55. Ialso'prefer to provide a spring 56 and a rod 57 pivotally connectedwiththe disk 53, so that when the disk is swung across the throat of thebinder head the spring 56 will be put'unaer tension i to return thedisk.to its normal position. The. disk 53, in addition to its functionofraising and supporting the 'cord,.al so clears 1: V
